I'm not sure, but I have to say there is some merit in these days.
Fridays most people are just thinking about the weekend
Mondays people need time to get back into the grind and start thinking about what they can do to get out of their ruts. So Tues, Wed & Thurs might be the sweet spot.
Just my opinion.
Every second is the same on the internet.
I have heard Tues, Wed & Thurs are best. Any thoughts and/or personal test results? Thanks in advance!
